Title:
FLOW CONTROLLING DEVICE AND LIQUID WEIGHING DEVICE
Document Type and Number:
Japanese Patent JP2015117829
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a flow controlling device capable of easily controlling a flow rate of liquid in a microchannel device, and capable of being easily manufactured.SOLUTION: A flow controlling device 1 includes a film 6, and a gas generation film 7 made of an optical responsive gas generating agent. A linear and bottomed slit 17 is provided on a surface of the film 6. Both ends of the slit 17 face microchannels 2a and 2b. The slit 17 is closed when not used. Gas is generated by irradiating light to the gas generation film 7, and a pressure by the gas is imparted from a rear surface side of the film 6. Accordingly, the film 6 is deformed, and the slit 17 is opened. Liquid can flow into or flow out of the microchannels 2a and 2b through the slit 17.
